GRATE STRUCTURE FOR GAS RANGES Filed Jan. 26. 1952 United States PatentGRATE STRUCTURE FOR GAS RANGES Henry Honer, Los Angeles, Calif.,assignor to Western Stove Company, Inc., Culver City, Calif, acorporation of California Application January 26, 1952, Serial No.268,417

4 Claims. (Cl. 126-215) My invention relates to grate structures for.gas ranges, and included in the objects of my invention are:

First, to provide a grate structure for gas ranges which comprises apair of complementary coplanar grate members, each capable of being usedindividually as well as in conjunction with each other.

Second, to provide a grate structure for gas ranges which, when thegrate members are used individually, provides either a small grate forsmall cooking vessels, and a large grate for large cooking vessels, eacharranged to expose direct to the burner flame a portion of the cookingvessel, and further provides, when both grate members are used together,a protective wall between the flame of the burner and the cooking vesselto facilitate low temperature cooking.

With the above and other objects in view as may appear hereinafter,reference is directed to the accompanying drawings in which:

Figure l is a plan view of the inner grate member.

Figure 2 is a plan view of the outer grate member.

Figure 3 is a plan view of the two grate members as arranged forconjunctive use.

Figure 4 is a transverse sectional view through 4-4 of Figure 3 showingfragmentarily a burner and mounting ring with which the grate structureis used.

An inner grate member 1 is provided which is in the form of a platehaving radiating projections 2. In the structure shown, six suchprojections are provided. Secured to the underside of three of theseprojections are radiating legs 3. The inner ends of the legs 3 mayunderlap the projections and spot welded thereto. The legs arepreferably channel shaped in cross section and terminate in rounded,downwardly-turned feet 4.

An outer grate member is provided. This member is in the form of a flatdisk provided with a central opening 6, the margin of which comprises aseries of recesses 7 separated by radially inwardly directed projections8. The pattern formed by the central opening 6 coincides with themargins of the inner grate member 1 so that the outer grate member maybe fitted over the inner grate member as shown in Figure 3. When soarranged, the grate members are coplanar and present a substantiallysolid surface broken only by the relatively narrow slit formed betweenthe confronting margins of the two grate members. The outer grate memberis provided with feet 9, corresponding to the feet 4. In the structureshown, three of such feet 9 are provided and are adapted to be locatedmidway between the feet 4. The upper surfaces of the legs 3 may serve toaid in the support of the outer grate member indicated in Figure 4.

In practice, the grate members either individually or in conjunctionwith each other are adapted to rest on a mounting ring R which fitsaround a conventional range burner B. The margins of the ring R areprovided with a rib to aid in centering the grate members.

Having fully described my invention, it is to be understood that I donot wish to be limited to the details herein set forth, but my inventionis of the full scope of the appended claims.

I claim:

1. A grate structure for cooking ranges, comprising:

a mounting ring adapted to be disposed in concentric relation with acooking range burner, said mounting ring having an annular supportingsurface bordered by a retaining rim; an inner grate plate having aplurality of radially outwardly directed fingers; radiating legsprotruding beyond alternate fingers and downtourned at their extremitiesto form supporting feet adapted to rest on the supporting surface ofsaid ring and be retained within said rim; an outer grate plate circularin outline and having a plurality of radially inwardly directed fingersintermeshing with the fingers of the inner plate whereby said plates maybe disposed coplanar-1y; and downtourned feet extending from theperiphery of said outer grate plate and, when said plates areintermeshed, disposed between the supporting feet of the inner grateplate and also adapted to rest on the supporting surface and to beretained within the rim of said mounting ring.

2. A grate structure for cooking ranges, comprising: a first outer grateplate having a central opening, the margins of which form alternateradially inwardly directed projections and radially outwardly directedrecesses; a second inner grate plate conforming to and filling saidopening, said grate plates being coplanar; and a set of radiatingsupporting feet for independent support of each of said grate plates,each of said grate plates being operable independently of the other aswell as simultaneously operable.

3. A grate structure for cooking ranges, comprising: a first outer grateplate having a central opening, the margins of which form alternateradially inwardly directed projections and radially outwardly directedrecesses; a second inner grate plate conforming to and filling saidopening, said grate plates being coplanar; a first set of radiating feetfor said inner second grate plate extending under and beyond said outergrate plate; and a second set of radiating feet for said outer grateplate, said sets of radiating feet providing independent support of saidgrate plates, each of said grate plates being operable independently ofthe other as well as simultaneously operable.

4. A grate structure for cooking ranges wherein each burner is providedwith a concentric mounting ring having a marginal supporting surface andsurrounding rim, comprising: an inner grate plate having a plurality ofradially outwardly directed fingers; radiating legs protruding beyondalternate fingers and downtourned at their extremities to formsupporting feet adapted to rest on the supporting surface of said ringand be retained within said rim; an outer grate plate circular inoutline and having a plurality of radially inwardly directed fingersintermeshing with the fingers of the inner plate whereby said plates maybe disposed coplanarly; and downturned feet extending from the peripheryof said outer grate plate and, when said plates are intermeshed,disposed between the supporting feet of the inner grate plate, and alsoadapted to rest on the supporting surface and to be retained within therim of said mounting ring.
